Among the different characteristics of 21st Century learning, collaborative learning is mentioned over and over again. I don't think that learning collaboratively is a unique feature of our times, however, with the increase of social networks and other sites which enable collaboration, this dimension of learning is indeed more in the spotlight.
One tool which caters for collaboration is the online whiteboard and today's suggestions are some which are freely available.
IDroo - to use with Skype
If you would like to collaborate with documents, these sites are easy to edit, to use individually or to share:
Mo Pad - an ether pad
For iPads, why not try out Show Me Interactive Whiteboard and
Zig Zag Board - both free to download.
Learning may be up to the individual, but the process of learning does not mean that it has to be a lonely experience. It is through interaction with others that one learns, practices and defines one's self-knowledge and awareness.
What other whiteboards for collaboration would you suggest?
